EDIT

almost 100% fixing #2950 (Allow grouping of lucene (hibernate search) results) - only max score is not yet available

javadoc

toString for Collection

now really fixing #3119 (fulltext search: Entity always null whatever search)

new enumeration CdmBaseTypes.java : Enumeration of all abstract CDM base types. Each provides a set of all sub types

fixing NPE and test to reproduce #3113 (hibernate search: wildcard query can cause BooleanQuery: maxClauseCount is set to 1024)

avoiding id unnecessary fields in the lucene index

avoiding id duplication in lucene index, circumvents a bug in hibernate-search

fixing #3115 (search method : TaxonServiceImpl.findTaxonByDescriptionElementFullText() is missing Distributions) + test for #3063 (hibernate search: CdmMassIndexer.purge() fails, it does not empty the index.)
